'GRADING-MACHINE.

Specification of Letters ZEatent. P t t d A us, 1915,,

Application filed February 7, 1914. Serial No. 817,268.

To all whom it may/concern Be it known that I, CLARK B. FELL, a citi zen of the United States, resident ofNorthfield, county of 'Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Grading-Machines, of which the following is a specification, the principle of the invention being herein explained and f the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. Y

My invention relates to grading machines,

its object being to provide a' grading ma-' chine Which may be economically manufactured and which will be eflicient in its use.

Specific objects of the invention are to provide a grading machine which may bev used in grading soil of all characters, which may be readily turned around, andwhich will require a minimum power for, its operation.

The said invention consists of. means hereinafter fully described and particularly set forth in the claims. y

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be employed.

In said annexed drawings :Figure 1 represents a plan of a grading machine embodying my invention; Fig. 2 represents a vertical transverse section taken, upon the planes indicated by lines II.II in Fig; 1. Fig. 8 represents a side elevation of the ma chine. Fig. t represents, upon an enlarged scale, a fragmentary side elevation with parts broken away, illustrating the means for raising and lowering the frame. Fig; 5 represents a vertical transverse section, partly in elevation, taken upon the planes indicated by lines V-V in Fig. 4.. Fig. 6 represents a detail .vertical' section of the bearing-block and crank-arm together with the upper end of the supporting rod used for raising and lowering the plow-arm. 7

The illustrated embodiment of my invention comprises a main frame 1 of general rectangular form, on the left side of which, as viewed in Fig. 2, and extending upwardly and transversely, is suitably mounted an elevator or conveyer 2. This elevator consists of the usual belt 3, made of canvas or other suitable material, the said belt running around suitable rollers 4, 4;, in thefusual in the art.

ing and driving wheel 5 suitably mounted upon the frame and beneath the elevator, as

shown in Fig. 2. The elevator and means for operating same form no part of my present invention and it is therefore deemed unnecessary to describe same in detail, since the manner of mounting and operating such an elevator is well-known to those skilled Secured on the right-hand inside of the front member 6 of the main frame, is a supporting casting 7 provided with lugs 8, 8, between which is supported the front end of an'oscillatory plow-arm 9, the said end being suitably secured by means of a pin 10, Fig. 1. This armextends backwardly and at an angle toward the elevator, as shown, and upon its free end is mounted a plowdisk 11 which rotates freely. Suitably secured'to the plow-arm 9 is a scraper 12 for scraping the 'soil from the interior of the plow-disk. This scraper and the details of construction thereof form no part of my therefore be 13. The upper end of this rod extends through an oscillatory bearingblock 14, Fig. 6, a suitable bore 15 being provided through which the rod slides, said rod being provided with a cap 16 which prevents it from passing completely therethrough. This bearing-block is provided with trunnions 17, 17, which are mounted in bearings'18 formed in the end of a bifurcated crank-arm 19. Intermediately of the bearing-block 1 1 and plow-arm 9 and surrounding the rod 13 is a coil-spring 20.

It will be seen fromvthe above described arrangement of parts, that the plow-arm 9 may be caused to yield upwardly when the plow-disk meets any hard obstruction such as a stone, the spring 20 returning the arm and disk to its normal position when such obstruction is passed. I

The crank-arm 19 is secured to a longitudinally extending shaft 21 mounted upon the upper portion of an upwardly and longitudinally therefor extending auxiliary frame 22, the latter being suitably secured to themain frame 1. To the front end of this shaft is secured a gear-segment 23 whose teeth mesh with a worm 24; secured to a transversely extending shaft 1 25 to which is secured a suitable hand-wheel 26, It will therefore be seen that by rotating the handwheel 26, the shaft 21 may be oscillated, so. 7

1 entire machine may be turned around within fa comparatively small area and it is there- 1 fore relativelyeasy of manipulation in this asto raise or lower the plow-arm 9 and th plow-disk attached thereto. p Having its upper end mounted in a bearing 27, Fig. 5, secured to the front portion of the side member 28 of the frame, ,isa downwardly extending axle-bar 29.

upper end of this bar is secured in the bearing 27 by means ofa collar 32 which Mounted upon the side member 28 is a ratchet-segment 3 1, Fig, 4, and pivotally mounted upon the said frame member 28 is an adjusting-lever 35 upon which is suitably mounted a pawl 36'adapted to engage the teeth 37 ,of the segment 3%, said pawl being held in normal engagement therewith by means of a suitable coil-spring 38, as will be understood. Having its upper end articulating with the adjusting-lever 35 is a bar 39 whose lower end articulates with a strap I .0 secured to the axle-bar 29 and near the lower end thereof. This axle-bar normally extends in an angular direction toward the rear, as shown in Fig. 4:- A suitable rod 41 and grip 42 are provided for actuating the pawl 36 in the usual manner. It will there fore be seen from the above described construction that the axle-bar 29 maybe oscillated in its upper bearing 27 and the frame 1 therefore raised or lowered with reference to the axis of the wheel 31.

Rigidly secured to the front of the main frame 1 and at about the middle of the transverse member 6 is a forwardly extending auxiliary frame 13 upon the forward end of which is pivotally mounted, by means of the king bolt 14, a front truck 45 provided with suitable wheels 46. This truck is. provided with the usual tongue 47 and auxoperated to lower the frame to the required position, the weight of the frame and parts connected therewith,- causing the plow-disk to'project into the soil. The machine then being drawn forwardly, the plow-disk 11 throws the earth upwardly and laterally to the left upon the traveling belt orelevator 2, the soil being thus discharged laterally ofthe entire machine on the left thereof,

from whence it may be discharged into a wagon or directly to the ground in the usual manner.

The lower end 30 of this axle-bar forms a jour-' nal for a side supporting wheel 31. They ed upon said frame andv extending trans.-

- vator, the additional supporting. wheel 31 at the side and the front truck in front and nearrthe .center, it will be l seen that the respect. g

It will also be seen that by the arrangement of parts whereby the main frame may 5 be raisedor lowered with reference to the side wheel 21 and the arrangement whereby I the'plow-armmay be raised and lowered,.a proper adjustment 'oftheplow disk is readily obtained. .Furthermore; as previously gq mentioned, when the plow disksmeets with" any hard obstruction such as a "'stone,*; the arm 9 will yield upwardly and permit said disk to passsuch lobstructiomafter a. 7

operatin position. Havin g fully.

which the, spring returns samefto its normal described inventi0n;-"
